A bit knocked flat by the heat, but here's some epic reportage on the multiplicitous business activities of the children of China's top leaders. These guys wouldn't hire Mark Thatcher as a butler.
I can see a looming nomenclature problem here around the tricky issue oif what term you use for the children of princelings. Maybe you could adapt the system in Brazilian football where you have Ronaldao (big Ron) Ronaldo (Ron) and Ronaldinho (little Ron). So by that, Winston Wen, Bo Guagua etc would be princelinginhos. Oh well. It's a thought.
